- Compensates for Reground Crankshafts: The primary, educational purpose of the MS-2350A-.25MM is to be used exclusively with a crankshaft that has been machined to a smaller diameter. The ".25MM Undersized" designation directly corrects the running clearance for these resurfaced journals.
- Critical Crankshaft Support: This set is fundamental to the engine's core function, providing firm support for the rotating crankshaft against the intense forces of combustion.
- Minimizes Frictional Drag: The bearings create a highly lubricated surface that dramatically reduces metal-to-metal friction, allowing the high-speed crankshaft to spin smoothly and efficiently, which translates to better power transfer.
- Engine Component Protection: By acting as a sacrificial wear surface, the bearings protect the much more expensive components—the crankshaft and the engine block's saddle bores—from catastrophic damage in the event of oil pressure loss or overheating.
- Superior Durability: Built with Clevite AL-Series construction, which utilizes a modern lead-free aluminum silicon alloy, the bearings deliver exceptional seizure resistance and wear characteristics, ensuring reliable, long-lasting performance for your rebuilt 6.7 Powerstroke.
Elevate the performance and longevity of your 6.7 Powerstroke engine (2011-2020) rebuild with the precision-engineered Clevite MS-2350A-.25MM Main Bearing Set. When a high-mileage or distressed engine undergoes a rebuild, the crankshaft's journals—the surfaces that ride within the main bearings—often show signs of wear, pitting, or scoring. To restore optimal function, a machinist must resurface and polish the journals, a process known as "regrinding," which slightly reduces the crankshaft's diameter. This undersized bearing set is the critical component needed to compensate for this reduction. With a precise inner diameter 0.25 millimeters (or .010 inch) smaller than standard, the MS-2350A-.25MM ensures the correct oil clearance and a perfect fit, which is absolutely vital for the smooth operation and long-term durability of your engine.
